PCNS Service doesn't start. PCNS Filter EventID 6004

I've installed the Password Change Notification Service ( x64 ) version 4.1.3114.0.  This was installed on an Active directory Domain Controller running Microsoft Windows Server 2008 R2 Enterprise version 6.1.7601 Service Pack 1 Build 7601.

I followed the directions to run the SCHEMAONLY=TRUE first then run the installer and restart.

After reboot I checked the logs and found the following error log below.

I've read various things including installing the version I already have or removing "" from the name of the executable listed in the registry--all of which have not resolved the issue.
